I was looking into the supported hardware that 9.1 will run on and FAS32xx series is shown, however, I noticed that the FAS3240 doesn't have a link to download 9.1. The FAS3250, however, does show an download link for 9.1.
What's not supported on the 3240 series to allow this to be upgraded? I have other FAS that can upgrade, however, my 3240 has some snapmirror relationships that I need to address if I cannot upgrade to the 9.1.x release.
I've wondered this for a long time as well. And to add, you're not the first person to ask this. I wish I could say I had a good answer, espically when you realize that the 3220 can upgrade to 9.1, but the 3240 can't. But from best I can tell is that there's slight differences in specs if you put it next to other 3200 series controllers.
Example. the 3220 has 24GiB of system memory and the 3240 only has 16GiB.
